PROBLEM TO BE SOLVED: To simply obtain a uniform optical characteristic, without adding a new unit, by coloring a protector for protecting an optical semiconductor element according to its optical characteristic to add a screen-filmy function to the protector. SOLUTION: Packages 102 contg. optical semiconductor elements i.e., light emitting elements are disposed like a matrix on a common matrix substrate 103 and have light-permeable protectors 101 made of a light permeable material e.g. epoxy resin. The protectors have different color densities. The optical output is measured when the light emitting elements are mounted in the package 102 and electrically wired. The elements providing a high optical output are combined with hyperchromic protector 101 and those providing a low output are combined with a hypochromic protector, thus the intensity of the light taken out from each emitting element through the protector 101 is made const. to reduce the dispersion of the optical characteristic. |
